Reduce PDF Image Quality: questions
- Will it work on a phone?
- Yes. The layout adapts to a small screen and the processing runs in the mobile browser, so a photo or a downloaded document can be handled on the device it arrived on.
- Why is it free?
- Because the expensive part — the server farm — does not exist. Processing runs on your device, so the site can stay free without a signup wall in front of it or an upsell in the middle of a job.
- Which file types does Reduce PDF Image Quality accept?
- The drop area takes PDF. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".
- What do I get back from Reduce PDF Image Quality?
- The result is PDF, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.
